The main and lateralconveyor nwmhrrs rmnprise essentially conveyor beds, and the removersproper comprise each a plurality of roir'cyer elements carried on a sngle iiltlltnri chain which is looped longivi 'iniali with respe t to amain convcyer nuinlwr and provided with a lateral loop liiilitllllg inconjunction with the corresponding lateral conveyor member.

Entering now more specifically into the structure of the body truck ofthe machine and truck comprises a frame 20 supported by the wheeledaxles 21 and carrying an engin-1* of any desired type, which providesthe motive power for the conveyors. Upstanding at the forward corners ofthe frame are a pair of standards 23 Which have their upper endsrearwardly curved and connected by a transverse beam 2a and supportedbetween the intermediate portions of the atandari 7 are a pair of hoppersectionsflti arranewl to discharge at the forward end of i l rnrli. Adjacent the tops of the hop )ers in standards carry forwardly extendingwhich carry a platform 26 on which the operator stands when operatingthe ma chine: For closing the hoppers when desired a closure gate 27 ishinged to the lower edges of the discharge mouths of the hopper andpivoted to this gate ontlt'vardly of and. iiiawnt its hinge connectionis a link f-ES s ivh extends to anangular lever 29 piva angle to theplatform and coactuteri m,

Thus between the rear end of the mainconveyer member and the lateral conveyer, the conveyer elements of thereturn stretch ride on the internualiate track bed 47 and between thelateral conveyer and the forward end of the main conveyor the elementsride on the conveyer bed 36 and in operation convey matorial thereupon.

The elements are retained in proper rela tion to the bed at the bend ofits inwardly directed portion by a series of idle sprocket wheels 112disposed. thereover at this point.

In the main loop of the conveyer, the plates 109 are disposed with theirscraper edges inwardly with respect to the main con- Voyei frame, andthus on the bed 46 he relaining walls 110 of the plates eAtend for--wardly and coact with the wall '(7 of the hell to form eoniliiartmenisholding the matrrial to be conveyed.
